- Kubeadm: Fixed a regression where the JoinConfiguration.discovery.timeout was no longer respected and the value was always hardcoded to "5m" (5 minutes). ([#125480](https://github.com/kubernetes/kubernetes/pull/125480), [@neolit123](https://github.com/neolit123))
- Kubeadm: Removed support for mounting /etc/pki as an additional Linux system CA location

* Increase allowed lag for ssh key sync loop in tunneler to allow for one failure ([#60068](https://github.com/kubernetes/kubernetes/pull/60068), [@wojtek-t](https://github.com/wojtek-t))
